remap_range is for remapping regions with different cache attributes.
It is implemented for ARM and PowerPC only, the other architectures only
provide stubs.
Currently the new cache attributes are passed in an architecture specific
way and the attributes have to be retrieved by calls to
mmu_get_pte_cached_flags() and mmu_get_pte_uncached_flags().
Make this simpler by providing architecture independent flags which can
be directly passed to remap_range()
Also provide a MAP_ARCH_DEFAULT flag and a arch_can_remap() function.
The MAP_ARCH_DEFAULT defaults to whatever caching type the architecture
has as default. the arch_can_remap() function returns true if the
architecture can change the cache attributes, false otherwise. This
allows the memtest code to better find out what it has to do.

In drivers/usb/core/usb.c we already have le16_to_cpus() conversion
just after usb_get_descriptor():
390 /* correct le values */
391 le16_to_cpus(&dev->descriptor->bcdUSB);
392 le16_to_cpus(&dev->descriptor->idVendor);
393 le16_to_cpus(&dev->descriptor->idProduct);
394 le16_to_cpus(&dev->descriptor->bcdDevice);
so no additional idVendor/idProduct descriptor fields
le16_to_cpu() conversion is needed after that.
On the big-endian machines extra le16_to_cpu() conversion
leads to wrong idVendor/idProduct USB device parameters values
(e.g. see devinfo <usb-device> output), and to a much more
serious problem: idVendor/idProduct-based USB device detection
does not work.

We used to support video modes directly in the ldb device node, that
was lost in: 5bda17e video: ipuv3: Replace ipu_output with VPL.
Add this support back. Also drop duplicate vpl ioctl forwarding for
several calls.
With this patch modes can either be retrieved from the ldb node as
originally done or from the panel remote port.

putting an error pointer into strerror can be a bit confusing since
strerror takes a positive error code but PTR_ERR returns a negative
number, so we have to do strerror(-PTR_ERR(errp)). Some places got
this wrong already, so introduce a strerrorp function which directly
takes an error pointer.

A read id operation followed by 0x00 reads the device ID while
a read id operation followed by 0x20 reads the possible ONFI identifier.
As the READID function did not propagate the second id parameter but had
a hard-coded call for 0x90 0x00, reading the ONFI identifier was not
possible and thus chips werde not detected (tested with
MT29F8G08ABABAWP)

The reference manual (for the i.MX25 in my case) states:
This field must start at a location that enables a complete
picture to be stored in a 4 Mbyte memory boundary (A [21:0]). A
[31:22] has a fixed value for a picture’s image.
Check this condition for user-supplied framebuffer values and enforce it
for driver-allocated buffers.

USB: introduce usb_interface/usb_configuration structs
On little endian systems like ARM the le16_to_cpus() macro
is a no op, defined as:
#define le16_to_cpus __le16_to_cpus
#define __le16_to_cpus(x) do {} while (0)
So struct usb_configuration field misuse was discovered
on big-endian MIPS machine.
